| Outline of Final Research Achievements |
Synthetic resins produced from various polymer compounds are used as materials for various products because they are inexpensive, highly durable, and easy to mold. On the other hand, it is difficult to firmly immobilize low-durability proteins on the surface of synthetic resins, because synthetic resins are highly durable. In this research, a new method for immobilizing proteins on the plastic surface was investigated using supercritical carbon dioxide which expands synthetic resins and improves the solubility of proteins and enzymes. In addition, the immobilization of directionally controlled proteins using peptide tags was also investigated.
